The 19-year-old signed for £28 million last summer from Southampton according to the Mail, and has admitted that the step up has been difficult. Manager Louis van Gaal has criticised his fitness levels since he arrived at Old Trafford, and he has had to spend periods on the sidelines with several injuries.

The left-back was substituted at half time during their defeat to Arsenal in the FA Cup last month, and was left out of the side for the following four games. He denies this was because of his boss being unhappy with him: “I saw a comment the other day saying I was taken off at half-time against Arsenal because I wasn’t fit enough, but that’s not true at all.

“This is coming from me and I know what the manager pulled me off for and it was not for my fitness because I could have carried on in the game.”

However, the defender does admit that he has been struggling to deal with the pressure since signing for the Premier League giants. The Mail now believe that he is seeing a psychologist as a result.

He said: “‘I am still young and coming to the biggest club in the world hasn’t been easy for me. I wouldn’t say it has been a hard three weeks but it has been a three weeks that I have been able to learn a lot more about myself, so it has been a nice three weeks in that respect and good to get on the pitch again.”
